Deere as an alterna- tive engine operating mode used to increase the DOC inlet tem- perature above 572°F to allow and maintain active regeneration. The increase in electronic control capability also carries over to ma- chine integration. For example, Stigler said the engine ECU — in con- cert with the vehicle electronics — can provide geo-fencing, a capability that can limit or halt engine perform- ance based on location of the piece of equipment. This is an anti-theft fea- ture available on some John Deere equipment. It allows the equipment to be severely de-rated or shut down if it is outside an owner-specified area. “Another example is integrated grade control for crawler dozers, which allows our customers a simpli- fied integration of grade-control sys- tems from outside suppliers,” Stigler said. “This reduces cost and im- proves the quality of integration.” Tom Withers, JDPS marketing com- munications manager, added that this integration is being used by JDPS engine distributors with their OEM cus- tomers. He pointed to a trash com- pactor application where the engine ECU was controlling and automating some of the hydraulic operations. “Our engine distributors are inte- grators,” Withers said. “While they have always designed engines into applications, for Tier 4 interim, they have enhanced their resources to deliver integrated solutions beyond the engine compartment.”The entire off-highway engine- powered equipment world learned some major lessons from the 2007 on-highway regulations and the re- sponse truck fleets had a raft of new technologies that suddenly seemed to come from nowhere. The response from truck users was loud, not gener- ally positive, and slowed sales of new vehicles significantly. The communication of the 2010 on- highway technologies was communi- cated much better, and the off-highway world learned from those examples. At Deere, these lessons resulted in an “extra effort” communication called the Dealer Readiness Program, ini- tially targeted at the John Deere equipment division dealers. The pro- gram started about 10 months ago, 18 months before the start of Tier 4 interim production. Its goal is to make sure dealer personnel are ready for Tier 4 interim, Withers said. “It covers every aspect of a John Deere agricultural, construction or forestry dealership — the shop, fuels and lubes, parts stocking, sales, service — literally everything,” Withers said. “The equipment divisions are con- tinuing to use all their normal commu- nication channels — bulletins, meet- ings, training and equipping field per- sonnel with information,” he said. “However, for Tier 4 interim, we’re tak- ing extra steps.” Deere has designated emissions/ engine individuals in each equipment division to manage the subject of emis- sions for those machines, Wither said. “For example, in the Ag & Turf divi- sion, an emissions technology inte- gration manager was established to
